Abstract
A turbocharger with integrated Exhaust Gas Recirculation (EGR) employs an EGR pump impeller mounted on a common shaft with the turbocharger compressor and turbine. The EGR pump is housed within an EGR extension in the bearing housing adjacent the compressor housing backplate. The recirculation extension includes an exhaust gas outlet for the pumped EGR and an exhaust gas inlet is incorporated in the backplate adjacent the EGR pump impeller.
